To all whom it may concern.'

Be it known that l, COLEMAN W. SUMNER, a citizen of the United States, residing at Texola, in the county of Beckham and State of Oklahoma, have invented a new and useful Petcock, of which the following is a specification.

This invention relates to an improved petcock particularly designed for use on the transmission casing of the well known Ford automobile. Two oil petcocks are used in the machine mentioned, one being located above the other. The lower one, however, often is thereby releasing the lubricating oil and resulting in injury to the bearings of the machine. lt is an object of the present invention to provide a petcock which can be substituted readily for the upper petcock already in use, and which has means for engaging the lower drain cock, thus to lock both valves against accidental opening.

With the foregoing and other view which will appear as the proceeds, the invention consists novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claim, it being understood that various changes may be made within the scope of the objects in description of certain appended claim without departing from the spirit of the invention.

In the accompanying drawing the preferred form of the invention has been shown.

ln said drawings- Figure l is a face view of a portion of the transmission casing of a Ford automobile and showing the present improvements applied thereto.

Fig. 2 is a side elevation of the improved structure, the adjacent portion of the casing being shown in section.

Referring to the ligures by characters of reference, l designates a portion of a transpopiee or this patent may te obtained tor nve cents each, by addressing the mission casing and 2 designates the usual lower drain cock used in connection therewith. The ordinary upper drain cock is removed and the device constituting the present invention is substituted therefor.

he improved cock 3 has a channeled strip 4 pivotally connected to the :flattened head thereof as shown at 5 and this strip is of sufcient length to engage and straddle the head of the cock 2 when the two cocks are in closed position. A coiled spring 5 is secured at one end to the strip et and at its other end of the stem 6 of the cock 3 at that end thereof remote from the head.

When it is desired to apply the present im provements to a Ford automobile, the upper drain cock is removed from the transmission casing and the improved cock 3 is substituted therefor. By turning the two cocks so that the channeled strip l will straddle the head of the lower cock 2, where it will be held by the spring 5, both cocks will be held in closed positions and to open either of them it is rst necessary to swing the strip 4L out of engagement with the head of the cock 2.

What is claimed iszlhe combination with spaced petcocks each having a stern and a flattened head, of a channeled 4strip pivotally connected to the head of oneof the petcocks and adapted to straddle the head of the other petcock, and a spring connection between sald strip and the stem of the head to which it is pivoted for holding the strip yieldingly in engagement with the other head.

lin testimony that ll claim the foregoing as my own, l have hereto affixed my signature in the presence of two witnesses.
